Any (somewhat) informed predictions on the opening of the road to Boundary Creek (MF Salmon) this year?

I've been invited on a May 28 trip that won't go if the road isn't open, and I have the option to accept an invite on a June 18 instead. Problem is, both is not an option (stupid work) and I prefer the group on the former. The latter needs a commitment prior to the Memorial weekend launch. Just trying to garner all the info I can before I make my decision...

And ya, I know...we should all be so lucky to have this sort of "problem" to deal with, huh.
